Diagnostic Trouble Code, known as DTC, helps discover a car’s problem. You can find the problem faster and fix it correctly if the signs and causes of these codes are known. But have you ever thought about what code P047 means on 6.0 Powerstroke?<\/p>\n\n\n\n

The code P0472 on 6.0 Powerstroke means there\u2019s an issue in the electrical circuit due to the exhaust back pressure sensor. Some significant reasons behind this DTC code are a defective exhaust back pressure sensor, faulty PCM, and power shortage.<\/strong><\/p>\n\n\n\n

Lack of engine power and crank-no-start problem are two prominent symptoms of the P0472 code. But don\u2019t be afraid of seeing these signs. So, Hold on to your seat to know the remedy of the code P0472 on 6.0 Powerstroke.<\/p>\n\n\n

\"How<\/figure>\n\n\n

What Does P0472 6.0 Powerstroke Code Mean?<\/h2>\n\n\n\n

P0472, a DTC code of a vehicle, refers to a complex electrical circuit due to a faulty back pressure sensor. Here is the breakdown of the code to increase your understanding.<\/p>\n\n\n\n

    \n
  • P<\/strong> = Powertrain, part of the system to move the car ahead (in this case, an electrical circuit)<\/li>\n\n\n\n
  • 0<\/strong> = a generic code according to SAE<\/li>\n\n\n\n
  • 4<\/strong> = Auxiliary emission control<\/li>\n\n\n\n
  • 72<\/strong> = It indicates a particular fault index (in this case, fuel and air metering of the vehicle engine)<\/li>\n<\/ul>\n\n\n\n

    You will solve fifty percent of the code if you can notice the symptoms in the early stage. Plus, the meaning of the symbols will give you a better understanding of finding an easy solution.<\/p>\n\n\n\n

    How Serious Is Code P0472 On 6.0 Powerstroke?<\/h2>\n\n\n\n
    \"\"<\/figure>\n\n\n\n

    The DTC code P0472 is not an extremely severe problem in your car right off the bat. Generally, it indicates a faulty circuit having issues with the back pressure sensor. As a result, the exhaust pressure sensor cannot send a signal to the electrical circuit.<\/p>\n\n\n\n

    Since it can\u2019t match the surrounding pressure, the signal from the pressure sensor is not correct. However, you can still operate your vehicle with this DTC code in an emergency.<\/p>\n\n\n\n

    Sometimes the mechanic identifies it as an issue of the exhaust gas recirculation. It\u2019s because of the position of the EGR valve and the back pressure tube. This code must be appropriately diagnosed to confirm the problem in the back pressure sensor.<\/p>\n\n\n\n

    The source of this code may be electrical or manual. However, you must fix the code before it becomes a severe issue and affect the overall performance of your car and engine.<\/p>\n\n\n\n

    What Causes P0472 Code On 6.0 Powerstroke?<\/h2>\n\n\n\n
    \"\"<\/figure>\n\n\n\n

    The error code P0472 indicates a defect in the car\u2019s electrical circuit due to a faulty back pressure sensor. Different reasons are responsible for this code.<\/p>\n\n\n\n

      \n
    1. Faulty exhaust back pressure sensor<\/strong><\/li>\n\n\n\n
    2. Partly or wholly open exhaust back pressure sensor<\/strong><\/li>\n\n\n\n
    3. The exhaust back pressure sensor circuit has a bad electrical connection<\/strong><\/li>\n\n\n\n
    4. Blockage of the tube connecting the pressure sensor to the exhaust manifold<\/strong><\/li>\n\n\n\n
    5. Defective Power Control Module (PCM)<\/strong><\/li>\n\n\n\n
    6. Service engine soon warning light<\/strong><\/li>\n\n\n\n
    7. Power shortage in the signal circuit<\/strong><\/li>\n\n\n\n
    8. Open space between PCM and exhaust pressure supply in power supply<\/strong><\/li>\n\n\n\n
    9. Loose wirings between the back pressure sensor and exhaust manifold<\/strong><\/li>\n<\/ol>\n\n\n\n

      Other Symptoms Of Getting P0472 Code On 6.0 Powerstroke?<\/h2>\n\n\n\n

      Knowing some different symptoms makes it easier to identify the code faster. So before you try to find a solution, look for these symptoms to confirm the P0472 code in your vehicle.<\/p>\n\n\n\n

      Here are the signs to verify the P0472 code.<\/p>\n\n\n\n

        \n
      • The engine doesn\u2019t have enough power to start<\/strong><\/li>\n\n\n\n
      • Manual regeneration is not feasible<\/strong><\/li>\n\n\n\n
      • No renewal leads to crank-no start problem<\/strong><\/li>\n\n\n\n
      • Check engine light ON<\/strong><\/li>\n<\/ul>\n\n\n\n

        How To Fix P0472 Code On 6.0 Powerstroke?<\/h2>\n\n\n\n
        \"\"<\/figure>\n\n\n\n

        Fixing the P0472 code on 6.0 Powerstroke is not impossible. You can solve this issue by just setting the symptoms and causes behind this code.<\/p>\n\n\n\n

        However, the standard solutions for this code are fixing the defective wires in the EPS, removing the code from memory, checking the sensors and circuits, and observing and inspecting the EPS voltage.<\/p>\n\n\n\n

        You can\u2019t follow the common fixes to crack the P0472 code if it gets complicated. Instead, an experienced mechanic will help you to solve the code smoothly.<\/p>\n\n\n\n

        Here are the steps a mechanic follows to crack the P0472 code.<\/p>\n\n\n\n

        1. Reprogramming<\/h4>\n\n\n\n

        The mechanic will reprogram or flash the protocol.<\/p>\n\n\n\n

        2. Inspecting The Sensors<\/h4>\n\n\n\n

        Next, he checks the back pressure sensors, wirings, connectors, and bare wires.<\/p>\n\n\n\n

        3. Replacing Defective Materials<\/h4>\n\n\n\n

        Then he looks for corroded or burnt materials to replace them with new ones.<\/p>\n\n\n\n

        4. Checking The Power Supply Circuit<\/h4>\n\n\n\n

        Detaching the harness and exhaust pressure sensor connection using a DVOM, a mechanic inspects the power supply circuit to check if there\u2019s enough power to run the sensor.<\/p>\n\n\n\n
